Abstract: Theoretical mechanics is a basic course for students majored in engineering. To improve the academic challenge level, increase the difficulty of the course, and expand the depth of the course, the course has to be carefully arranged. After the depth and the breadth of basic courses are expanded, the follow-up professional courses are expanded, with regard to the teaching links, the teaching content, the teaching methods, as well as the practice links, to make a "golden class" for the theoretical mechanics.
